3-aryl-2-phosphoryl-1-indanones have been synthesized from β-ketophosphonates and aromatic aldehydes via corresponding chalcones, in a selective Horner–Wittig or Knoevenagel olefination, followed by a Nazarov cyclization. In preliminary tests, the final compounds and the intermediate chalcones revealed anticancer activity against HeLa and K562 at the μM level.
3-Aryl-1-indanones 和一组以前未知的 3-aryl-2-phosphoryl-1-indanones 已经从 β-酮膦酸酯和芳香醛通过相应的查耳酮在选择性的 Horner-Wittig 或 Knoevenagel 烯化中合成,然后是纳扎罗夫环化。在初步测试中,最终化合物和中间体查耳酮在 μM 水平显示出对 HeLa 和 K562 的抗癌活性。
